Abstract
A noise rejection circuit for an implantable pacemaker. During re-triggerable relative refractory periods following a heartbeat, the peak noise level is sensed; the relative refractory period is re-started whenever the input signal exceeds the previous peak. Following a time-out of the relative refractory period, the peak value detected, representing the noise level, is added to the programmed threshold value; the sum is used as the threshold value during sensing.
